Abstract
A radar apparatus has an inclined slot wave guide array to form a narrow azimuth beam and a dielectric lens in front of the array to form a narrow elevation beam. The radar apparatus is particularly useful for motor vehicular collision warning systems. The inclined slot wave guide forms an antenna which is driven to oscillate back and forth at a small angle. The dielectric lens is fixed in position relative to the slotted wave guide antenna. The combination of the slotted array for forming a narrow horizontal pattern in combination with the dielectric lens for forming a vertical pattern provides an arrangement that is readily scannable.
